[PATCH 01/12] s390x/pci: use a reserved ID for the default PCI group |
Date: |
Tue, 7 Dec 2021 16:04:14 -0500 |
The current default PCI group being used can technically collide with a
real group ID passed from a hostdev. Let's instead use a group ID that
comes from a special pool (0xF0-0xFF) that is architected to be reserved
for simulated devices.
